Missing space before instanceof operator

[naraesk]

What steps will reproduce the issue?

Format the following code.

if (a.get() instanceof B st) {
}

What is the expected result?

Nothing should change.

What happens instead?

The space before instanceof is removed in IntelliJ using the Eclipse Code Formatter, i.e. the output is

if (a.get()instanceof B st) {
}

With Eclipse 2020-06 this does not happen.
As far as I can tell no setting in Eclipse or IntelliJ has influence on the output.

Without the st at the end, the formatting is correct.

Paste information about IDE and OS (it can be copied from Help | About dialog).

Tested on Arch Linux and Windows.

It can be also reproduced with a current Eclipse 2022-02 formatter profile. The problem only happens if parentheses are before instanceof.

Following code is formatted correctly:
if (a instanceof B st) { }

Did you find any solution to this ? @DanielWebelsiep

This bug has been fixed for Eclipse version 4.22 M1 (https://bugs.eclipse.org/bugs/show_bug.cgi?id=574437). Therefore, updating the bundled Eclipse installation should fix this bug.
